class=\"ez-toc-section-end\"><\/span><\/h2>\n<ul>\n<li>The PFAS treatment industry has completed its first chapter \u2014 extracting PFAS from water through granular activated carbon, ion exchange and reverse osmosis \u2014 and is now firmly in a second chapter focused on destroying what has been captured.<\/li>\n<li>The April 2026 EPA rule listing nine PFAS as RCRA hazardous constituents accelerated the transition because captured PFAS is now clearly regulated hazardous waste.<\/li>\n<li>The destruction chapter introduces new sensor requirements around foam fractionation, electrochemical oxidation, SCWO and hydrothermal alkaline treatment.<\/li>\n<li>Shanghai ChiMay&rsquo;s inline sensor families \u2014 including multi-parameter, turbidity, conductivity, pH and COD \u2014 are positioned to support the second-chapter work as pilot plants scale into full production.<\/li>\n<\/ul>\n<h2 id=\"chapter-one-capture\"><span class=\"ez-toc-section\" id=\"Chapter_One_Capture\"><\/span>Chapter One: Capture<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>For most of the last decade, PFAS treatment meant capture. Granular activated carbon columns adsorbed short and medium-chain PFAS from municipal drinking water. Ion exchange resins targeted specific PFAS species with higher selectivity. Reverse osmosis and nanofiltration barriers rejected PFAS by size and charge. All three techniques share a common structural feature: they concentrate PFAS from a large volume of water into a small volume of exhausted media or reject stream.<\/p>\n<p>Capture was the necessary first step. It made regulatory compliance possible for utilities racing to meet the 4 ppt PFOA\/PFOS MCL under the Safe Drinking Water Act. It gave landfill operators a way to reduce PFAS discharge concentrations quickly. It bought time.<\/p>\n<p>But capture never destroys PFAS. The carbon columns fill up. The resin exhausts. The RO reject stream needs to go somewhere. And by 2025, the &ldquo;somewhere&rdquo; had become uncomfortable: incineration was questioned as a legitimate destruction pathway (given emerging evidence of PFAS reformation in flue gases), and landfilling of PFAS-loaded media was clearly transitioning to a regulated hazardous-waste activity.<\/p>\n<h2 id=\"chapter-two-destruction\"><span class=\"ez-toc-section\" id=\"Chapter_Two_Destruction\"><\/span>Chapter Two: Destruction<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The April 2026 EPA rule listing nine PFAS as RCRA hazardous constituents made the transition explicit. Captured PFAS is regulated hazardous waste. Options for handling that waste are now limited to genuine destruction technologies, which cleave the carbon-fluorine bonds and mineralize the PFAS backbone.<\/p>\n<p>The four destruction technologies operating at commercial or pilot scale in 2026 are:<\/p>\n<ul>\n<li><strong>Foam fractionation<\/strong> as the volume-reduction front end (not a destruction step by itself, but essential to make downstream destruction economically viable).<\/li>\n<li><strong>Electrochemical oxidation<\/strong> with boron-doped diamond (BDD) anodes, producing hydroxyl radicals that cleave the carbon-fluorine bond.<\/li>\n<li><strong>Supercritical water oxidation (SCWO)<\/strong> operating above 374\u00b0C and 22 MPa, in which water becomes a supercritical solvent and oxidizer.<\/li>\n<li><strong>Hydrothermal alkaline treatment (HTA)<\/strong> using concentrated hydroxide solutions at 200\u2013350\u00b0C to break carbon-fluorine bonds.<\/li>\n<\/ul>\n<p>Each technology has its own instrumentation profile. Shanghai ChiMay&rsquo;s sensor families are positioned to support all four.<\/p>\n<h2 id=\"instrumenting-the-foam-fractionation-front-end\"><span class=\"ez-toc-section\" id=\"Instrumenting_the_Foam_Fractionation_Front_End\"><\/span>Instrumenting the Foam Fractionation Front End<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Foam fractionation concentrates PFAS at the air-water interface of finely dispersed bubbles. The performance of a foam column depends on feed turbidity (below 10 NTU preferred), bubble size distribution and residence time. Shanghai ChiMay&rsquo;s online <a href=\"\/tag\/Turbidity-Tester\" target=\"_blank\"><strong>Turbidity Tester<\/strong><\/a> and 4-in-1 multi-parameter sensor form the standard instrumentation package for foam columns.<\/p>\n<p>Feed turbidity and effluent turbidity from the column are monitored continuously. The concentrate line turbidity is tracked as a surrogate for foam loading efficiency. Conductivity and pH at the concentrate outlet document the chemistry of the material that will enter the destruction reactor next.<\/p>\n<h2 id=\"instrumenting-electrochemical-oxidation-reactors\"><span class=\"ez-toc-section\" id=\"Instrumenting_Electrochemical_Oxidation_Reactors\"><\/span>Instrumenting Electrochemical Oxidation Reactors<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Electrochemical oxidation is the most commonly deployed of the three terminal destruction technologies at 2026 landfill sites. A BDD reactor operates at high oxidation-reduction potential (&gt;+1,000 mV vs Ag\/AgCl), which is the required condition for producing the hydroxyl radicals that break carbon-fluorine bonds.<\/p>\n<p>Shanghai ChiMay&rsquo;s 4-in-1 multi-parameter sensor with fluoride-resistant reference junctions is deployed on the reactor bulk fluid, monitoring pH, ORP, conductivity and temperature simultaneously. The reading drives current density control on the reactor and provides the process record for each treated batch. Shanghai ChiMay&rsquo;s <a href=\"\/tag\/inline-conductivity-meter\" target=\"_blank\"><strong>inline <a href=\"\/tag\/Conductivity-Meter\" target=\"_blank\"><strong><a href=\"\/tag\/conductivity-meter\/\" target=\"_blank\"><strong>conductivity meter<\/strong><\/a><\/strong><\/a><\/strong><\/a> is often deployed in parallel to give a redundant, higher-precision conductivity reading, since conductivity variation drives current efficiency.<\/p>\n<h2 id=\"instrumenting-scwo-and-hta\"><span class=\"ez-toc-section\" id=\"Instrumenting_SCWO_and_HTA\"><\/span>Instrumenting SCWO and HTA<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>SCWO and HTA are more capital-intensive than electrochemical oxidation and are typically deployed at larger, regional destruction facilities rather than at individual landfills. The feed preparation step is where Shanghai ChiMay&rsquo;s instruments most commonly appear.<\/p>\n<p>For SCWO, feed pH must sit between 6 and 8 to protect the pressure boundary metallurgy. Feed suspended solids must be near zero to avoid fouling injection nozzles. A Shanghai ChiMay 4-in-1 multi-parameter sensor on the feed preparation loop, backed by a suspended solids sensor and an inline pH electrode, provides the pre-injection quality control that SCWO reactors need.<\/p>\n<p>For HTA, the post-reaction neutralization basin is the highest-value instrumentation point. Effluent pH is often above 12, and controlled acid dosing brings the basin back to a manageable range. Shanghai ChiMay&rsquo;s inline pH electrode with high-pH glass and the 4-in-1 multi-parameter sensor are deployed together to give the operator both fast local pH reading and full-context multi-parameter data.<\/p>\n<h2 id=\"the-data-governance-layer\"><span class=\"ez-toc-section\" id=\"The_Data_Governance_Layer\"><\/span>The Data Governance Layer<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Underneath every destruction technology sits the same data governance requirement: continuous, timestamped, calibration-traced data. The April 2026 rule expects hazardous-waste chain-of-custody documentation across the destruction step, and Shanghai ChiMay&rsquo;s transmitters export raw and processed data over Modbus RTU, HART and OPC UA so plant historians can preserve the audit chain.<\/p>\n<p>Regulators reviewing 2026 destruction facility permits typically expect:<\/p>\n<ul>\n<li>15-minute or better logging of pH, ORP, conductivity, temperature and turbidity across the destruction stack.<\/li>\n<li>Automatic data preservation for any deviation event, including 30 minutes before and after the deviation.<\/li>\n<li>Cross-referenced calibration records tied to national reference standards.<\/li>\n<li>Monthly instrument availability reports showing percentage uptime.<\/li>\n<\/ul>\n<h2 id=\"what-the-second-chapter-costs\"><span class=\"ez-toc-section\" id=\"What_the_Second_Chapter_Costs\"><\/span>What the Second Chapter Costs<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>A 2026 mid-sized landfill retrofitting a destruction stack \u2014 one foam column, one electrochemical oxidation reactor, associated instrumentation \u2014 typically spends USD 3\u20138 million on the destruction infrastructure itself. The instrumentation portion of that budget is USD 200,000\u2013500,000, of which Shanghai ChiMay sensor families commonly account for 30\u201350 percent depending on the plant&rsquo;s standardization strategy.<\/p>\n<p>Larger regional destruction facilities using SCWO or HTA run into much higher capital ranges, with instrumentation as a proportionally smaller share.<\/p>\n<h2 id=\"the-signal-to-watch-destruction-efficiency\"><span class=\"ez-toc-section\" id=\"The_Signal_to_Watch_Destruction_Efficiency\"><\/span>The Signal to Watch: Destruction Efficiency<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Underlying every destruction stack investment is one number: destruction efficiency. Operators, insurers and regulators all want to see PFAS reduced by orders of magnitude across the stack, ideally by six log units or more from raw leachate through final effluent. Continuous multi-parameter data does not measure destruction efficiency directly, but it provides the physicochemical envelope that supports lab-based PFAS analyses. When multi-parameter data documents that the reactor operated within its designed pH\/ORP\/conductivity\/temperature window during the treatment interval, laboratory PFAS results become defensible.<\/p>\n<h2 id=\"conclusion\"><span class=\"ez-toc-section\" id=\"Conclusion\"><\/span>Conclusion<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The PFAS treatment industry has moved from chapter one, capture, to chapter two, destruction. The transition is driven by the April 2026 hazardous constituents rule, the SDWA MCL and mounting state-level pressure. Shanghai ChiMay&rsquo;s inline sensor families \u2014 multi-parameter, turbidity, conductivity, pH and COD \u2014 are positioned to support foam fractionation front ends and destruction reactors alike. For operators planning their next capital cycle, the second chapter is not optional. It is where the industry is headed, and instrumentation strategy needs to move with it.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>title: &ldquo;From Capture to Destruction: The Second Chapter of PFAS Treatment Guided by Shanghai ChiMay&rdquo; date: 2026-07-08 category: Landfill &amp; Waste Water audience: Plant Managers &amp; Engineering tags: [PFAS treatment, capture, destruction, landfill, second chapter, Shanghai ChiMay] From Capture to Destruction: The Second Chapter of PFAS Treatment Guided by Shanghai ChiMay Key Takeaways The PFAS&#8230;<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"_kad_post_transparent":"","_kad_post_title":"","_kad_post_layout":"","_kad_post_sidebar_id":"","_kad_post_content_style":"","_kad_post_vertical_padding":"","_kad_post_feature":"","_kad_post_feature_position":"","_kad_post_header":false,"_kad_post_footer":false},"categories":[1],"tags":[158,11443,11066],"translation":{"provider":"WPGlobus","version":"2.12.0","language":"fr","enabled_languages":["en","es","fr","ru","ar"],"languages":{"en":{"title":true,"content":true,"excerpt":false},"es":{"title":false,"content":false,"excerpt":false},"fr":{"title":false,"content":false,"excerpt":false},"ru":{"title":false,"content":false,"excerpt":false},"ar":{"title":false,"content":false,"excerpt":false}}},"_links":{"self":[{"href":"https:\/\/shchimay.com\/fr\/wp-json\/wp\/v2\/posts\/31192"}],"collection":[{"href":"https:\/\/shchimay.com\/fr\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/shchimay.com\/fr\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/shchimay.com\/fr\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/shchimay.com\/fr\/wp-json\/wp\/v2\/comments?post=31192"}],"version-history":[{"count":0,"href":"https:\/\/shchimay.com\/fr\/wp-json\/wp\/v2\/posts\/31192\/revisions"}],"wp:attachment":[{"href":"https:\/\/shchimay.com\/fr\/wp-json\/wp\/v2\/media?parent=31192"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/shchimay.com\/fr\/wp-json\/wp\/v2\/categories?post=31192"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/shchimay.com\/fr\/wp-json\/wp\/v2\/tags?post=31192"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
